From Seattle-area design firm MK7, the brand new PIRANHA, is a single-piece, multi-purpose pocket tool constructed from heat-treated and corrosion-resistant S30V stainless steel with a neoprene double-ended driver bit holder built right in -- perfect for tightening screws, loosening bolts, opening beers, and sabotaging the car of that guy who made that joke about you also being a pocket tool.
